Whole Foods is busy on Instagram in the hours before it opens the store at 1860 Bayview at Broadway Aves. The titillating Twelve thirty-six @1236 tweets: “Like the artisanal Tim Hortons up there — the people of Leaside like being reminded they’re in Leaside.” Yes, yes. That means having the look of an artisan, but we appreciate the thought. The new Whole Foods opens Wednesday, April 26 at 8.45 a.m.
